LTC2376IDE-16#PBF

Analog To Digital Converters (ADC) Overview

The LTC2376IDE-16#PBF is a 16-bit, 250ksps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. Operating from a single 2.5V supply, it features a fully differential input range of ±VREF with VREF spanning 2.5V to 5.1V. The device achieves a typical SNR of 97dB and ±0.5LSB maximum INL with no missing codes at 16 bits. Power consumption is 3.4mW at full throughput, scaling down to 3.4µW in power-down mode. It includes an internal oscillator, SPI-compatible serial interface supporting 1.8V to 5V logic, and a digital gain compression function.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #PBF indicates lead-free finish and tube packaging. Confirm the IDE suffix corresponds to the industrial temperature range of –40°C to 85°C and the DFN package type. Ensure compatibility with the required VDD and OVDD voltage levels during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a low-power, high-speed 16-bit ADC is required with a fully differential input. The digital gain compression feature is critical if the driving amplifier must operate from a single positive supply. Verify that the host system supports the SPI-compatible serial interface and can handle the 1.8V to 5V I/O voltage requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2376-16 family of low power SAR ADCs. The IDE suffix specifically denotes the industrial temperature grade (–40°C to 85°C) and the 16-lead (4mm × 3mm) plastic DFN package. Other variants include CMS for commercial MSOP and IMS for industrial MSOP packages.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2376CDE-16#PBF (commercial temp) and LTC2376IMS-16#PBF (industrial temp, MSOP package). Cross-package substitution requires PCB layout modification.
